Hidden Hercules Actor Kevin Sorbo reveals his secret battle with stroke. By Linda Childers

O

n the iconic television show Hercules, actor Kevin Sorbo played the title role. His portrayal of the muscle-bound demigod was so convincing that many viewers came to associate Sorbo with his on-screen persona. Almost no one knew that Sorbo had suffered a series of strokes during the course of filming the popular series, which aired from 1994 to 1999. This month, for the first time, the 52-year-old actor reveals the story behind his health crisis and recovery to Neurology Now and in his new book, True Strength: My Journey from Hercules to Mere Mortal and How Nearly Dying Saved My Life (October 2011, De Capo Press).

Strange Sensations Sorbo, who grew up in Minnesota, played football, baseball, and basketball in high school and college. As an adult, he worked out regularly at the gym and completed his own fights and stunts on the set of Hercules. It wasn’t until the summer of 1997, at the age of 38, that his health took a bizarre and unexpected turn. Out of the blue, he began experiencing troubling symptoms in his left arm and hand, including intermittent pain, aching, tingling, and cold sensations. “At the time, I was promoting the feature film Kull the Conqueror. I had several doctors on my publicity tour check me out, but they didn’t believe it was anything serious,” Sorbo recalls. “I even had what seemed like a rational explanation, having recently injured my ulnar nerve—the funny bone.” Satisfied that his symptoms were benign and would soon pass, Sorbo continued his strenuous workouts until one day, while lifting weights, he felt a searing pain shoot down his left shoulder. Thinking he may have suffered a strain, he made a same-day appointment with his longtime chiropractor. “After an examination, he told me I had a lot of tightness in p h oto g r a ph s by a n n jo h a n s so n

Aneurysm: The Basics

T Sorbo’s Aneurysm and Strokes Driving home, Sorbo began to experience blurry vision, dizziness, and buzzing in his head. He decided to sleep it off. But the next morning, his speech was slurred and he could barely walk. (See box, “The Signs of Stroke,” page 79.) His fiancée, actress Sam Jenkins, took him to the hospital, and after a flurry of tests, doctors determined he had severe disruption of blood flow to his lower arm caused by an aneurysm in an artery near his shoulder. An aneurysm is an abnormal widening or ballooning of a portion of an artery due to weakness in that artery’s wall. (See box, “Aneurysm: The Basics.”) “Apparently, the aneurysm had been producing blood clots for some time. I had blockages all down my arm that were making my fingers cold, tingly, and numb,” Sorbo remembers. Franklin Moser, M.D., a neurologist at Cedars-Sinai Medical Center in Los Angeles, told Sorbo that of the two main arteries that feed the hand, one of his was completely blocked. Dr. Moser scheduled a surgical procedure where an angiogram tube would be used to insert platinum coils around Sorbo’s aneurysm. “He explained the blood would then clot around the coils and adhere to the walls of the aneurysm, effectively neutralizing it,” Sorbo recalls. “I was told that within several weeks the aneurysm would be side-lined or ‘clotted off.’ The coil clots would form a new arterial wall that would allow blood to flow through the area normally.” Although not a conventional treatment for a shoulder aneurysm, Dr. Moser explained that it was a less invasive procedure, Sorbo says. Only after the procedure would MRI tests show that Sorbo had suffered three distinct strokes, accounting for his dizziness and vision loss. One of his other doctors suggested that Sorbo’s clots may have traveled in reverse, toward his brain. However, the precise cause of his strokes remains unknown. “I was told clots don’t typically travel ‘upstream’—in reverse to the brain—so my doctors were unsure whether the aneurysm was related to the strokes,” Sorbo says. “I began to wonder whether having my neck cracked had somehow exacerbated my condition.” Sorbo’s doctors considered his experience a medical anomaly. They told him that someone of his age and physical health had about a one in seventy-five million chance of experiencing both an aneurysm and strokes.

 Certain genetic disorders  High blood pressure  Cigarette smoking  Atherosclerosis, a condition in which an artery wall thickens as a result of the accumulation of fatty materials such as cholesterol  Head injury  Infection Aneurysms can also occur in the aorta (the main artery that carries oxygen-rich blood from the heart to the body) and in other arteries of the body. Having an aneurysm in the shoulder, as in the case of Kevin Sorbo, is uncommon. The National Institute of Neurological Disorders and Strokes (ninds.nih.gov) places the incidence of reported ruptured aneurysm at about 10 in every 100,000 persons per year (about 27,000 individuals per year in the U.S.), most commonly in people between ages 30 and 60 years. Possible risk factors for rupture include hypertension, alcohol abuse, drug abuse (particularly cocaine), and smoking. “Most cerebral aneurysms do not show symptoms until they either become very large or burst,” Dr. Kirshner says. “If the aneurysm does rupture, patients report having the worst headache of their life as well as the sudden onset of neck pain and stiffness.” Signs that a cerebral aneurysm has burst:  Headache  Neck pain and stiffness  Nausea and vomiting  Drooping eyelid  Sensitivity to light  Change in mental status or level of awareness  Seizures “People who experience the ‘worst headache,’ especially combined with these other symptoms, need to get prompt medical attention,” Dr. Kirshner says. “Prompt medical attention for patients with a cerebral aneurysm that has burst, or with a stroke, leads to a better outcome,” Dr. Kirshner says. The most effective therapies for blocked-vessel (ischemic) stroke are clot-busting drugs such as tPA. A stroke needs to be treated as soon as possible and no more than 4.5 hours after stroke onset to be be eligible for intravenous tPA.

ihe most common aneurysm that neurologists see is a saccular cerebral aneurysm, in which a weak or thin spot on a blood vessel in the brain balloons out, forming a tiny sac or bubble off the side of an artery that then fills with blood,” Dr. Brown says. “A brain aneurysm can leak or rupture, causing bleeding into the brain. This is known as a hemorrhagic stroke.” Although many aneurysms do not have a specific cause, the various types of aneurysms that occur in the brain can sometimes be caused by:

Did Chiropractic Adjustment Play a Role?


always at his side Sorbo’s wife Sam convinced him to try psychotherapy to help him cope with the anxiety and depression he experienced after his strokes.

Sorbo found he was sensitive to many of the medications’ side effects, and he quit taking them. “Depression is a very common yet relatively undiagnosed after-effect of having a stroke,” Dr. Brown says. “Depression and anxiety, which often occur together, are very treatable symptoms. They can typically be improved through medication or a combination of psychotherapy and medication.” Sorbo admits that psychotherapy helped him cope with his illness more positively, including the fact that his recovery period was taking much longer than his doctors had anticipated. He also learned that his feelings of anxiety and depression were a natural response to the psychological trauma of stroke, and he found some relief through acupuncture treatments. “As a result of working with an acupuncturist, I improved dramatically,” Sorbo says. “My headaches and dizziness were less severe and more manageable as well.”

An Everyday Kind of Hero included balance board exercises and ball tosses to improve his reflexes and coordination. A year after his strokes, he married Sam. She had stood by his side through the entire ordeal. Still, his progress inched along, which increased his frustration. Sorbo’s hours on the set of Hercules were limited, and even the simplest of filming tasks proved challenging. Used to working 12-hour days, the actor was now lucky to put in a couple of hours on set. “A patient’s recovery after a stroke or aneurysm can vary quite a bit, based on a number of factors—for example, the patient’s age, overall health, and how much brain tissue was damaged,” says Robert Brown, M.D., chair of the neurology department at the Mayo Clinic in Rochester, MN, and a Fellow of the AAN. “And the length of recovery can vary dramatically on a case by case basis.” The National Institute of Neurological Disorders and Stroke notes that for some stroke survivors, rehabilitation is an ongoing process and can involve working with specialists for months or even years after the stroke. “I went through two years of hell before I began to feel like myself again,” Sorbo says. “I was depressed and frustrated and had a bad attitude.” In addition to regaining his health through physical rehab, Sam convinced her husband to address the emotional aspects of his condition through psychotherapy. While doctors had prescribed different anti-anxiety and antidepressant medication, w w w.n e u rolo gy now.co m

Today, Sorbo has regained his health, although he still experiences residual arm pain from the circulation loss and nerve damage. Two post-stroke symptoms—the occasional migraine and a 10-percent blind spot with his vision—continue to affect him. “Headaches are common after strokes, and may feel migrainelike because of new circulatory pathways,” says Dr. Kirshner. “Also, tears in the vertebral artery often cause neck and shoulder pain and headache. Vision loss after stroke is often permanent if an area of the brain called the occipital cortex is damaged.” The father of three young children, Sorbo has resumed an active lifestyle. He has received critical acclaim for his role in the recent film Soul Surfer; in addition, he has several movies in post-production and is working on a television pilot. In 2010, Sorbo starred in What If, nominated for Best Family Movie of the Year 2011 by the Movieguide Awards. Sorbo also received the Movieguide Award for Most Inspirational Performance of the Year for his role in the movie. The actor credits his recovery to his wife, his strong religious faith, and his determination not to let his health problems get the best of him. He hopes that by sharing his story, he will inspire others who have suffered from aneurysm or stroke. “My illness made me special in a way that I never wanted nor expected,” Sorbo says. “I’m not Hercules; I’m a mere mortal with human limitations and problems. But I am determined to not behave like a victim anymore.” And that can take an exNN traordinary kind of strength. Neurology now
